In organic chemistry, Direct C-H functionalization that converts C-H bond to reactive C-X bond has studied actively. In homogeneous catalysis, many studies about C-H functionalization have proceeded. However, heterogeneous catalysis, there are much fewer studies about C-H functionalization than homogeneous catalysis because of neutral metal state (0) of metal nanoparticles. Recent year, Glorius and co-workers reported that selective C-H direct arylation using diaryliodonium salts and proposed mechanistic studies proceeding via a Pd(o)/Pd(II) systems. But they didn’t confirm mechanism of C-H arylation. In this presentation, we report surface activation of palladium nanoparticles via diaryliodonium oxidants and mechanistic studies of direct C-H arylation of heterocyclic compounds using various analysis tools such as XPS, XAFS, TEM, etc.
